Product Overview
This 1000 ppm Lanthanum ICP-ML single-element standard delivers exceptional purity and consistency for demanding analytical applications. Prepared in a high-purity nitric acid matrix (2-5% HNO₃), the solution ensures minimal matrix interference while maintaining long-term stability. The standard is manufactured under ISO 17034 and ISO/IEC 17025 accredited processes, with full NIST traceability to guarantee measurement reliability. Each batch undergoes rigorous multi-point calibration verification using primary reference materials, ensuring accuracy within ±1% of the certified value. The solution is filtered through 0.2 µm membranes to eliminate particulate contamination, making it ideal for sensitive ICP-OES and ICP-MS instrumentation. Packaged in HDPE bottles with tamper-evident seals, the standard maintains its integrity during storage and transport. The 24-month shelf life when stored at 15-25°C provides extended usability without degradation. The low background impurity profile (<10 ppt for most elements) prevents spectral interferences, while the optimized acid concentration balances solubility and instrument compatibility. This standard is particularly valuable for laboratories requiring precise lanthanum quantification in complex matrices, where matrix effects and spectral overlaps demand high-purity reference materials.
FAQs
1. What is the exact matrix composition of this Lanthanum standard?
The standard is prepared in 2-5% high-purity nitric acid (HNO₃) with 18.2 MΩ·cm deionized water, ensuring complete dissolution while minimizing matrix effects during analysis.
2. How does the packaging prevent contamination during storage?
The solution comes in HDPE bottles with tamper-evident seals and PTFE-lined caps, using materials tested for leachables to maintain purity throughout the 24-month shelf life.
3. Can this standard be used for both ICP-OES and ICP-MS applications?
Yes, the 1000 ppm concentration is optimized for both techniques, though dilution may be required for ICP-MS to stay within the linear range of most instruments.
4. What certification documentation is provided with each batch?
Each bottle includes a certificate of analysis with traceability information, certified values, uncertainty statements, and expiration date, all compliant with ISO Guide 31.
5. How should this standard be handled to maintain accuracy?
Use with polypropylene or PTFE labware to prevent contamination. Avoid repeated opening of the bottle—aliquot into secondary containers if frequent access is needed.
